What does "Stone of Evolution" do exactly?

Top Voted Answer

It makes a Robo or Dragon into their adult form.

For those pets, when you first buy them, they are egg. When the egg reaches level 5 it hatches into the baby form. Once the Baby Form reaches level 15, you bring the stone of evolution to the Pet Specialist in NLC (He is also in Singapore) and you will get a random adult form of that pet.
